A series of 6-bromo-2,3-dioxoindolin phenylacetamide derivatives was synthesized and
evaluated for inhibitory activity against CDC25B and PTP1B. Most of the synthesized compounds
showed potential inhibitory activities for CDC25B and PTP1B with compound 12 being the most potent
(IC50=3.87 µmol/L and 2.98 µmol/L, respectively). Compound 12 also exhibited higher cytotoxic activity
against three cancer cell lines (HeLa, A549 and HCT116). In addition, compound 12 delayed the potent tumor inhibitory activity
in a colo205 xenograft model in vivo.

reverse transcriptase inhibitors (NNRTIs) are recommended components of preferred combination antiretroviral therapies used for the treatment of human immunodeficiency virus (HIV) infection. These regimens are extremely effective in suppressing virus replication. Recently, our research group identified some N1-aryl-2-arylthioacetamido-benzimidazoles as a novelclass of NNRTIs. In this research work we report

The copper-catalyzed highly regio- and stereoselective 1,1-dicarbofunctionalization of terminal alkynes is realized for the first time. Using a removable, bidentate 8-aminoquinoline auxiliary, the three-component, selective 1,1-arylalkylation of alkynes with α-haloacetamides and organoboronic acids by the addition of both alkyl and aryl groups to the terminal carbon of alkynes was achieved. Mechanistic

the limelight as a novel fungicide, and has fungicidal activity against Botrytis cinerea. For exploring more novel structures, 33 new compounds were synthesized by N-alkylation and acid-amine coupling reactions with chesulfamide as the core moiety, and their structures were characterized and established by ¹H-NMR, 13C-NMR, MS, and elemental analysis.
